1. A flow path assembly of a gas turbine engine, the flow path assembly comprising:
an outer casing comprising a metal material having a first coefficient of thermal expansion;
a ceramic structure comprising a ceramic material having a second coefficient of thermal expansion, the ceramic structure including a turbine blade portion, wherein the ceramic structure comprises an attachment flange extending radially outward therefrom;
a mounting component having a first end of a third coefficient of thermal expansion attached to the outer casing and having a second end of a fourth coefficient of thermal expansion attached to the ceramic structure at a location radially outward of the turbine blade portion, wherein the mounting component is constructed from at least two different materials transitioning from the first end to the second end such that the third coefficient of thermal expansion is different from the fourth coefficient of thermal expansion; and
an attachment mechanism extending within the attachment flange and the mounting component to attach the mounting component to the ceramic structure.
